Array | A grouping or array of disk drives combines the storage space on the disk drives |
| into a single segment of contiguous storage space. MegaRAID can group disk |
| drives on one or more SCSI channels into an array. A hot spare drive does not |
| participate in an array. |
Array Management Software Software that provides common control and management for a disk array. Array Management Software most often executes in a disk controller or intelligent host bus adapter, but can also execute in a host computer. When it executes in a disk controller or adapter, Array Management Software is often called firmware.
Array Spanning Array spanning by a logical drive combines storage space in two arrays of disk drives into a single, contiguous storage space in a logical drive. MegaRAID logical drives can span consecutively numbered arrays that each consist of the same number of disk drives. Array spanning promotes RAID levels 1, 3, and 5 to RAID levels 10, 30, and 50, respectively. See also Disk Spanning.
Asynchronous Operations Operations that bear no relationship to each other in time and can overlap. The concept of asynchronous I/O operations is central to independent access arrays in
